		Quoting <a href="https://yal.cc/docs/gm/window_shape/#window_enable_per_pixel_alpha">my own notes</a> from window_shape,
		</p><p>
		This function calls
		<a href="https://learn.microsoft.com/en-us/windows/win32/api/dwmapi/nf-dwmapi-dwmenableblurbehindwindow">DwmEnableBlurBehindWindow</a>
		for a zero-sized region.
		</p><p>
		Doing so also happens to enable partial transparency support for the contents of the window
		("The alpha values in the window are honored").
		</p><p>
		For example, if you did
		</p><pre class="gmlmd">
<span class="sf">draw_clear_alpha</span><span class="op">(</span><span class="sv">c_black</span><span class="op">,</span> <span class="nu">0</span><span class="op">)</span><span class="op">;</span>
</pre><p>
		in a Draw event of the only instance in a room, your window would look like an empty frame.
		</p><p>
		For a proper setup, make sure that
		"Clear Display Buffer",
		"Enable Viewports" (with at least one view set up),
		and "Clear Viewport Background"
		are enabled for the room;
		see <code>desktop_friend</code> project for a slightly more sophisticated example.
		</p><p>
		Now let's talk about the conditions and caveats:
		</p><section><header>Premultiplied alpha</header><article><p>
			Windows expects the window pixels to have premultiplied alpha.
			</p><p>
			In short, instead of just <code>color</code>, the pixels should be colored with
			</p><pre class="gmlmd">
<span class="sf">merge_color</span><span class="op">(</span><span class="sv">c_black</span><span class="op">,</span> <span class="sv">color</span><span class="op">,</span> <span class="uv">alpha</span><span class="op">)</span>
</pre><p>
			For sprites, all recent GameMaker versions have a "Premultiply alpha" checkbox
			in the Texture Settings;
			</p><p>
			For text and primitives, you'll need to use the above formula;
			</p><p>
			For mixing multiple semi-transparent images together, see the classic
			GameMaker surface problems and solutions.
			</p><p>
			If you don't use pre-multiplied alpha, your window will still work,
			but the semi-transparent bright portions will appear lighter than they should be.
		</p></article></section><section><header>Hit testing</header><article><p>
			According to Windows, just because a pixel is now almost or completely transparent,
			that doesn't mean that you can't click it!
			</p><p>
			You can use the extension's other functions (be it <s>shapes or</s> chromakey)
			to narrow down the window's shape, or use the
			<a href="#winwin_set_clickthrough">winwin_set_clickthrough</a> function
			to make the window clickable/un-clickable
			based on where the cursor is.
		</p></article></section><section><header>One-way ticket</header><article><p>
			The function has been around since Windows 7,
			yet it doesn't seem like you can go back to an opaque window
			once you have called it - even if you pass <code>dwFlags</code> of <code>0</code>.
			</p><p>
			You can "top-up" the opacity of the window contents by drawing a black rectangle
			with <code>bm_add</code> blend mode or any rectangle with <code>gpu_set_colourwriteenable</code>
			(or <code>draw_set_colour_write_enable</code> for GMS1) of <code>(0, 0, 0, 1)</code>.

	<li><p>	If the user has set up a custom Max Frame Rate override in NVIDIA Control Panel,
		the limit works as (value / active window count) instead.
		</p><p>
		The underlying cause seems to be that NVIDIA driver counts <code>Present</code> calls
		on per-process basis rather than per-window.
		</p><p>
		I haven't come up with a Cool Workaround for this yet,
		but if the user has set up it themselves, they can also remove the override.
